My fast charge is broken since 7.0. takes hours to charge from 60-100%. in the past when pull down menu, can touch to see how long to fast charge & it was fairly accurate. maybe charged a bit faster than stated. So If it said full charge in 35 min it may actually be 33 min. Now it will say charge in 47 min & takes hours.
I use Samsung fast charger & cable that came with phone. No, my charger &/or cable did not mysteriously break the day after the 7.0 update. I also dislike the look/feel of the 7.0. Much harder to see icons, text. Edge screen contacts now all look the same, lost the different colors. Light blue tiny icons against white background. When tap a contact to make call, get TINY icons to choose between text/call, why?
Wish I never updated.
